Real estate in Virginia is assessed at 100 percent of its fair market value. Real property tax bills are based on the real property assessment and the real property tax rate, which is set annually by the Board of Supervisors.

Personal property tax is levied each calendar year on all motor vehicles, trailers, campers, mobile homes, boats and airplanes if it is registered to a county address with the Virginia Department of Motor Vehicles.
